“…1,2 The market for styrene continues to expand with the current yearly output estimated at 30 million tons. 3 Traditional production of styrene has been via the dehydrogenation of ethylbenzene over iron oxide catalysts, and the epoxidation of propylene with ethylbenzene hydroperoxide. 3 However, excess dehydrogenation of ethylbenzene can lead to the production of phenylacetylene (PA), which is very tough to separate from the styrene stream owing to their analogous properties.…”

A minute amount of PA in the monomer acts as a cross-linker and as a brake on chain growth.…”

Phenylglyoxylic acid (PGA), as a urine metabolite of ethylbenzene and styrene (EB/S), can effectively represent the level of EB/S ingested by the human body through oral inhalation and skin absorption. Compared with measuring EB/S levels directly in the environment, detecting the level of PGA in urine has the advantages of high specificity and noninvasive sampling. In this paper, a metal-organic framework (MOF)-based sensor Zn-PBA = ({[Zn(PBA)ÁH 2 O]Á 2H 2 O} n , H 2 PBA = 4-(5-pyridinyl)-1,3 benzoic acid) for trace detection of PGA was designed and synthesized by a solvothermal method. Zn-PBA could detect the level of PGA in normal human physiological urine environment (pH range from 5.5 to 7.5) and has the characteristics of high selectivity and sensitivity, rapid response (<210 s), low limit of detection (LOD = 1.96 Â 10 À6 M), and so forth. The irreversible sensing of PGA proves that PGA caused the structural collapse of Zn-PBA. This paper provides a specific sensor for detecting trace PGA level for evaluating the EB/S content intake by the human body.
